[. . . ] SHARP will not be liable nor responsible for any incidental or consequential economic or property damage caused by misuse and/or malfunctions of this product and its peripherals, unless such liability is acknowledged by law. o Press the RESET switch (on the back), with the tip of a ball-point pen or similar object, only in the following cases. · When using for the first time · After replacing the batteries · To clear all memory contents · When an abnormal condition occurs and all keys are inoperative. If service should be required on this calculator, use only a SHARP servicing dealer, SHARP approved service facility, or SHARP repair service where available. DEG/RAD/GRAD: Indicates angular units and changes each time G is pressed. [. . . ] In addition, the four basic arithmetic operations and memory calculations can be carried out using the sexagesimal system. Notation for sexagesimal is as follows: · If the value for floating point system does not fit in the following range, the calculator will display the result using scientific notation system: 0. 000000001 | x | 9999999999 Determination of the Angular Unit In this calculator, the following three angular units (degrees, radians, and grads) can be specified. DEG (°) 123. 404080 degree minute Note: When the calculation or conversion result is converted, a residual may occur. second Press G GRAD (g) RAD (rad) Coordinate Conversions · Before performing a calculation, select the angular unit. Y y 0 x X P (x, y) Y P (r, ) r 0 STATISTICAL CALCULATIONS Press @ Æ to select statistics mode. The following statistics can be obtained: x sx x n x x2 Mean of samples (x data) Sample standard deviation (x data) Population standard deviation (x data) Number of samples Sum of samples (x data) Sum of squares of samples (x data) X Rectangular coord. Polar coord. BINARY, OCTAL, DECIMAL, AND HEXADECIMAL OPERATIONS (N-BASE) This calculator can perform the four basic arithmetic operations, calculations with parentheses and memory calculations using binary, octal, decimal, and hexadecimal numbers. When performing calculations in each system, first set the calculator in the desired mode before entering numbers. It can also perform conversions between numbers expressed in binary, octal, decimal and hexadecimal systems. Conversion to each system is performed by the following keys: Ï ê : Converts to the binary system. "BIN", "OCT", and "HEX" disappear from the display. Conversion is performed on the displayed value when these keys are pressed. Note: In this calculator, the hexadecimal numbers A ­ F are entered by pressing E, Ñ, /, ´, I, and l, and displayed as follows: F A B C D E Data Entry and Correction Entered data are kept in memory until @ Æ or F are pressed. [Data Entry] Data k Data * frequency k (To enter multiples of the same data) [Data Correction] Correction prior to pressing k: Delete incorrect data with ª. Correction after pressing k: Reenter the data to be corrected and press @ J. · The number displayed after pressing k or @ J during data entry or correction is the number of samples (n). Statistical Calculation Formulas In the statistical calculation formulas, an error will occur when: · the absolute value of the intermediate result or calculation result is equal to or greater than 1 × 10100. · an attempt is made to take the square root of a negative number. A å, B , C ç, D , E é, F In the binary, octal, and hexadecimal systems, fractional parts cannot be entered. When a decimal number having a fractional part is converted into a binary, octal, or hexadecimal number, the fractional part will be truncated. Likewise, when the result of a binary, octal, or hexadecimal calculation includes a fractional part, the fractional part will be truncated. In the binary, octal, and hexadecimal systems, negative numbers are displayed as a complement. ERROR AND CALCULATION RANGES Errors An error will occur if an operation exceeds the calculation ranges, or if a mathematically illegal operation is attempted. An error can be cleared by pressing ª. Calculation Ranges · Within the ranges specified, this calculator is accurate to ±1 of the least significant digit of the mantissa. However, a calculation error increases in continuous calculations due to accumulation of each calculation error. (This is the same for yx, x¿ , ex, ln, etc. , where continuous calculations are performed internally. ) Additionally, a calculation error will accumulate and become larger in the vicinity of inflection points and singular points of functions. [. . . ] Este equipamento obedece às exigências da directiva 89/336/ CEE na sua versão corrigida pela directiva 93/68/CEE. Este aparato satisface las exigencias de la Directiva 89/336/ CEE modificada por medio de la 93/68/CEE. Denna utrustning uppfyller kraven enligt riktlinjen 89/336/EEC så som kompletteras av 93/68/EEC. Dette produktet oppfyller betingelsene i direktivet 89/336/EEC i endringen 93/68/EEC. [. . . ]
